Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a support structure for a skirt rubber for a conveyor.

[Conventional technology]

BACKGROUND ART Conventionally, when a powdery or granular material is transferred by a belt conveyor, a skirt rubber is installed upright along the end of the conveyor belt so that the powdery or granular material does not overflow.

As a support structure of this skirt rubber, as shown in FIG. 3, support substrates B and B are arranged along the end of the conveyor belt A, and skirt rubbers C and C are mounted on the support substrates B and B by bolts and nuts D. Those fixed by are generally known.

However, this type of attachment structure has a drawback that the attachment adjustment is troublesome because the attachment adjustment must be done by detaching and attaching the bolt nut when the lower end of the skirt rubber is worn by friction with the surface of the conveyor belt.

In order to eliminate such drawbacks, instead of fastening with bolts and nuts, a wedge E is used as shown in FIG. 4 (for example, U.S. Pat. No. 55-136710), or a skirt as shown in FIG. The rubber C is housed in a bracket F having a U-shaped cross section with a downward opening, and the skirt rubber is always in contact with the surface of the conveyor belt A by its own weight (for example, JP-A-60-244714), or the skirt. It has been proposed that the rubber be sandwiched between guide rollers, and that the skirt rubber be adjusted in vertical position by rotating the guide rollers to cope with wear (for example, Japanese Utility Model Publication No. 52-112080). ing.

[Problems of conventional technology]

However, in the case of the former mounting structure using the wedge E, there is a risk of loosening due to vibration, and when the skirt rubber is mounted and adjusted, the skirt rubber may be displaced due to the driving of the wedge E, so that fine adjustment of the position is possible. There is a problem that it becomes difficult, and in the latter case, the skirt rubber C due to its own weight.
The skirt rubber has almost no vertical supporting force of the skirt rubber, and when powder particles are caught between the conveyor belt surface and the skirt rubber lower end, a skirt rubber is formed. There was a problem that the function of was damaged.

Also, in the case where the skirt rubber can be adjusted up and down by the roller, the skirt rubber is moved up and down only by the frictional force between the roller and the skirt rubber. Alternatively, there is a drawback that abnormal wear may occur in the skirt rubber.

[Problems to be solved by the device]

In view of the above-mentioned drawbacks, the present invention has been made for the purpose of providing a support structure for a conveyor skirt rubber which is easy to adjust its position and has sufficient support strength in the vertical and lateral directions.

[Technology that has solved the problem]

That is, the conveyor skirt rubber supporting structure of the present invention is constructed such that the rigid substrates are erected in parallel along both side edges of the belt conveyor surface in pairs without touching the lower edge to the belt conveyor surface. A rotating shaft is axially supported on the surface of each substrate in the length direction of the substrate, and a plurality of gears having a diameter that does not contact the substrate are coaxially provided on the rotating shaft.
Between the surface of the gear and the surface of the substrate, there are rack teeth meshing with the gear on the surface, and the bottom edge is made to face the surface of the belt conveyor, and a skirt rubber is sandwiched and supported in a compressed state. A rotary drive handle is provided at one end of the rotary shaft.

〔Example〕

 Next, an embodiment of this invention will be described.

1 is a side view of the embodiment of the present invention, and FIG. 2 is a side view of FIG.
FIG. 11 is a sectional view taken along line II-II.

The conveyor skirt rubber supporting structure of the present invention is designed so that a rigid substrate 1 such as a steel plate or a stainless steel plate along both side edges A ₁ of the surface of the belt conveyor A does not contact the lower edge 2 with the surface of the belt conveyor A. Conveyor A both ends (only one end in the illustrated example) are paired upright in parallel,
A rotating shaft 4 is axially supported on each substrate surface 3 in the longitudinal direction of the substrate 1 (arrow P), and a plurality of friction wheels 5 ... 5 having a diameter not contacting the substrate 1 are coaxially provided on the rotating shaft 4. 5, the skirt rubber 6 is sandwiched between the surfaces of the gears 5 ... 5 and the surface of the substrate 1 with the lower end edge 6A facing the surface of the belt conveyor A, and the skirt rubber 6 has a gear 5 at a position in contact with the gears 5 ... 5. .. 5 is provided with rack teeth, and a rotary drive handle 4A is provided at one end of the rotary shaft 4.

The lower end surface of the skirt rubber 6 has a conveyor belt A.
It is cut diagonally along the surface of.

[Action]

In this invention, the skirt rubber 6 is sandwiched between the gears 5 ... 5 that mesh with the rack teeth and the substrate 1, so that the gears 5 ... 5 can be surely moved in the vertical direction by the rotation of the rotary shaft 4. Therefore, the position of the skirt rubber 6 can be adjusted simply by rotating the handle A.

At this time, the skirt rubber 6 can be contacted and supported without applying surface pressure to the surface of the conveyor belt A, and in this case, abrasion with the surface of the conveyor belt A can be significantly prevented.

Further, the lower end of the skirt rubber 6 is worn and the belt conveyor A
When there is a gap with the surface, handle 4A as described above.
Rotate to lower the skirt rubber 6 position.

〔effect〕

As described above, according to the present invention, the position adjustment of the skirt rubber can be very easily performed only by rotating the handle, and the fine adjustment can be easily performed.

Further, since the structure is simple, the conventional device has various practical effects such that it can be easily attached after the fact and can be easily implemented.
